The ability of operators and users to quickly and easily navigate interfaces and accomplish required tasks is fundamental to the creation of desirable, effective and safe products and services. Understanding the visual performance of trainees or users is often critical in determining key factors contributing to success or failure in the execution of these tasks. The evaluation of expert users can uncover strategies for success which can then be imparted to trainees. Specific failings in visual performance of trainees can often be quickly identified and corrected. In addition, user visual performance evaluation can point out deficiencies in the design of human operated controls in vehicles and machinery of all kinds, as well as computer software interfaces. Below are several ISCAN systems designed to characterize task-based visual performance in different contexts. Any of these platforms can be customized to meet the requirements of your application.
